Grade: CG-Si50

Mixture of CG-Si69 and carbon black

CG-Si50 (Mixture of CG-Si69 and carbon black) provides the same functionality as CG-Si69 while offering easier handling. As a rubber and tire additive, it improves the physical and mechanical properties of rubber, enhancing tensile strength, tear strength, and wear resistance while reducing permanent deformation. Additionally, it reduces compound viscosity and improves processing performance.

Application

  • CG-Si50 is a mixture of CG-Si69 silane coupling agent and carbon black, providing the same functionality as CG-Si69 while offering easier handling

  • CG-Si50 acts as a rubber and tire additive to improve the physical and mechanical properties of rubber, enhancing tensile strength, tear strength, and wear resistance while reducing permanent deformation, and reduces compound viscosity to improve processing performance

  • CG-Si50 is suitable for polymers including natural rubber (NR), isoprene rubber (IR), styrene-butadiene rubber (SBR), butadiene rubber (BR), nitrile rubber (NBR), and ethylene propylene diene monomer (EPDM)

  • CG-Si50 is used in the white carbon black/carbon black modification industry for white carbon black/carbon black modification to promote subsequent dispersion in rubber, increasing the bound rubber content, wet skid resistance, and wear resistance of carbon black/rubber composites while reducing rolling resistance

  • CG-Si50 is used in the footwear rubber industry to improve the stability of rubber systems, enhancing yellowing resistance and increasing the tear strength of rubber used in shoe soles
